Trees are important to the environment, health and quality of life in our City.

One Million Trees Mississauga was launched to help conserve and enhance the City’s open spaces and forested areas for future generations to enjoy. Trees will be planted by City staff, partners and volunteers on public and private property. Residents who plant a tree on their private residential property can add it to our tree planting total and have it count towards our One Million Trees goal.

In Mississauga, there are 2.1 million trees on both public and private lands. Help us add one million more by 2032.

who should participate?

Everyone! Residents, businesses, schools, homeowners and community groups can all help us plant trees and reach our goal!

Why plant trees?

- Trees add beauty to our neighbourhoods;
- filter the air we breathe and the water we drink;
- help reduce energy costs and greenhouse gas emissions;
- improve storm water management;
- reduce impacts from natural tree decline or invasive species; and
- create a sense a neighbourhood pride.

Choosing the right plants is the key to successful planting! We recommend choosing native plants that will require low maintenance and will support the local wildlife. It is best to avoid invasive species.
